Normally file information and ID3 tags are retrieved when the file is being added to the playlist. Here you can select which types of files will have their information retrieved only when needed. This is handy if you have a slow CD-ROM drive, for instance.

Perform Open/Add/Insert Directory recursively

When this options is set, the directory additions will also traverse all sub-directories.

Sort directories by ID3 track number instead of filename

When this options is set, entries of added directories will be sorted by the TRACKNUM ID3 frame instead of the filename.

Delete tracks from the playlist after playing

When a track is played to its end and this option is set, the played track will be removed from the main playlist.

Stop playback after each track

This option causes the tracks to be played one by one.

Apollo will go through all the directories specified in the search path for sample space for track files when creating the sample space. See Apollo Advanced Playlist for details.

You can also set how many tracks Apollo will check back to prevent same tracks from playing too frequently.
